I was wondering about the status of the above topic:
Does a boost implementation of an adaptor exist or is Sebastian's
suggestion the best alternative currently available?

His solution did not work out of the box for me, since g++-4.6
complained about an

"incomplete type std::tuple_size<const std::tuple<..."

However, when I replaced each occurence of std::tuple_size<X> by

std::tuple_size< typename std::remove_cv<X>::type >

everything seemed to work fine.

Claas

No, there is nothing official, yet. I'll need code + docs before I
can add it to the library. Sorry, code only will not be enough.
Alas, I do not have time to do it. Best I can do is review the code
and docs, if anyone cares to submit.
